Planting this Fall? Remember to assess herbicide carryover risk

Before growers plant this fall, crop experts are encouraging them to evaluate their risk for possible herbicide carryover. The drought conditions for the 2012 growing season resulted in less herbicide degradation in soil, particularly with several different herbicide chemistries offered by multiple manufacturers.

Growers in impacted areas preparing to rotate to fall-planted crops, including winter wheat, can assess their risk for carryover by contacting their local retailers, BASF representatives or university extension specialists.

The following links provide information on herbicide carryover:

Unusual environmental conditions in 2012 have affected the risk of herbicide carryover. For growers that used Pursuit®, Extreme®, OpTill®, or OpTill® PRO herbicides in areas where drought occurred after application and where the grower is considering seeding winter wheat this fall, the possibility of injury to non-Clearfield® Production System wheat may be increased. For these areas, we recommend that growers select one of the following options:

Option #1:  Plant Clearfield® Production System winter wheat if a locally adapted variety can be sourced.
Option #2
:  Do not plant winter wheat. Plant corn, soybeans, or another rotational crop as recommended on the respective herbicide label.
Option #3
:  Moldboard plow and plant non-Clearfield® Production System winter wheat.

Understanding herbicide labels is key to helping assess crop rotation restrictions and potential crop response. To review BASF Crop Protection herbicide labels, please visit:
